| 摘要 |
The invention relates to a method for the formation of a protective film comprising a spinel of formula Mn x Co y O 4-´ , where x+y=3, on a metallic substrate, characterised in that it comprises the steps of:
a) depositing on the substrate manganese and cobalt as metal species in a molar ratio x/y corresponding to the above-mentioned formula by thermal co-evaporation; and
b) oxidising in situ the metal species to form the spinel. The method is applied in particular for the coating of metal interconnections for solid oxide fuel cells (SOFC). |
